JACK-ADJUSTER FOR LOOMS.

Specification of Letters Patent.

Iatented July 25, 1905.

Application filed January 17, 1905. Serial No. 241.406.

To all whom, it may concern.-

Beitknown thatI, J AMES DAWSON, a citizen of the United States, residingat Waltham, in-

which it appertains to make and use the same.

This invention relates to devices for adjusting the connection betweenthe harness-jack and the treadle in a loom; and it consists in the novelconstruction of the same, as hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of the jack-adjuster. Fig. 2 isa front view of the same.

A is a flat metallic bar provided at one end with two hooks arranged oneon each side of it, the hook B being at its extreme end on one side andthe hook C being on the other side and not quite at its extreme end. Dis a series of inclined projections on the other end. portion of the barA, which are on the same side of the bar as the hook B and which projecttoward the hook B.

This adjuster is intended to take the place of the leather strap orjack-strap commonly used to connect the harness-jack with the treadle.The projections D are connected with the jack, and the hooks B and Cafiord a means for connection with the treadle.

The hooks B and G are arranged out of line with each other for aboutone-half the distance between two adjacent projections D, and therebythe said hooks afford a finer adjustment than is possible with theprojections and a single hook. The projections cannot be placed veryclose together, as that would make them too thin and too weak.

What I claim is An adjusting device for a loom-harness, comprising a barhaving at one end a series of inclined projections, and having at itsother end two books arranged out of line with each other and affordingan intermediate adjustment.

In testimony whereof I have afiixed my signature in the presence of twoWitnesses.
